Look up LDNRearchTrust.org What is LDN? They have the latest research on this amazing drug. It is not yet FDA approved for the small doses we are using, just 50+ mg for opiate overdose. But its safety has been proven and FDA approval is just a matter of time. Right now, you need a script and a compounding pharmacy to get it. I've been on 2 mg since May 2019 and it has done amazing things for me. Stopped my non-moving pain in two days and healed my ulcerated small intestine in two months. Not for everyone but worth a try if you have a hyperactive immune system.
